Bodymedia grossly overestimates?

redheadmommy

I got a bodymedia for christmas , and I think it grossly overestimates my day. Does anybody else has this problem?
I started to use it right away on the 25th of December , which was just a few day after I gave birth to my baby. I lost a nice 10 lb in the first 6 weeks, and nothing ever since despite the vast calorie deficit estimated by my bodymedia.
I do not do any excersise except walking with the baby in the stroller.
Here is the last 28 days averages
Calorie burned 3058
Calorie consumed 2100
Deficit 958
Physical activity moderate 1:15 per day ( again only walking)
Steps 11163 ( I walk a lot)
Sleep duration 5:10 ( sleep deprivated new mom here)
The 3 month prior to this was pretty much the same and I practically have not lost weight in the last 4 months. My weight fluctuates 1-2 lb around the same weight I was 6 weeks postpartum.
I am exclusively breastfeeding , which supposed burn 500 calorie , which I am eating back. However even if that 500 calorie deduction for breastfeeding is wrong I still supposed to have 450 calorie deficit for the last 4 mnths , and I should be down 15 lb.

I do eat the recommended 1 g protein per lean bodymass, which is 125 g for me. I also played around with the carb and fat ratio. One month I ate 100g carb, other month I went 150 g carb , and 200g for the third month.
Still nothing! I am very frustrated to say the least. I measure my food usually by scale, and only use USDA entries on MFP or entres that I verify on the package. Still nothing!
Now what? The whole calorie in calorie out theory is a garbage and breatsfeeding mothers body do not work that way. Or my bodymedia and MFP grossly overestimates.
